After the 1989 Loma Prieta Earthquake, California has been rebuilding every bridge in the state that wasn't up to earthquake standards. The project is almost done, although the Foresthill Bridge near me is still under construction [this is one heckuva bridge - fourth-highest in the U.S. - and yes, I've walked it]. Mostly, the bridge reconstruction work appears to be quite satisfactory, but somehow the San Francisco Bay Bridge has been plagued with problems.
